Ibis Mtn. Trials, best rear tire recommendations

ibis owners, what do you ride on the rear of your mtn trials?

years ago i stashed away several 24" specialized ground controls to save for use as the rear tire on my ibis mtn trials... but over time my supply has dwindled; i'm down to just one more tire in the attic reserve. what, in your opinion, is the best 24" tire on the market these days? if it exists, i'm looking for a tire fit for real rides, with the volume and thread count and durometer to work on singletrack... i've tried several 24" bmx tires, literally on-and-off, over the years looking for an alternative, but i've found them all to be unbearably brutal and generally lame due to low thread counts, silly tread patterns, and hard rubber.
